Fountain Fills to PDF

Back in X5, when I printed a radial fountain fill (consisting of 2 spot colors) to pdf using Acrobat, the result would be one element (using the edit object tool in Acrobat or bringing into Illustrator).

Now in X7, using the identical settings and the same file, the result is a gazzillion separate lines.

Does anyone know if it's possible to get a single element?

Thanks so much!
